    Overpriced Phone with Annoying Issues

    |

    Posted . Owned for 1 month when reviewed.
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Phone is extremely overpriced, it should be worth around $700 at most. There are also literal ads within some apps - imagine paying for a phone (especially over $1000), thinking you own it, and still having ads playing inside the phone - this is alone enough for me not to want to use this phone. Some things people don't talk about: 1. Cameras are good but the UI in the camera software is not that great (except for Pro mode, which is pretty nice). 2. The software experience overall isn't very intuitive. There are some settings which are buried deep within the Settings app. It's also not very friendly with Google Photos (for example, every time you want to delete a photo using Google Photos, it will ask you via prompt if you're really sure you want to give Google Photos access). 3. Google Maps access - this is one of the most infuriating & potential harmful issues. Typically you'd imagine that any navigation apps (Google Maps, Waze, etc.) would need access to the phone's GPS all the time by default. This is not the case in this phone for some reason. When you open up Google Maps, it will ask you via a prompt if you want to give Maps access to the GPS either only this one time, only when the app is open, or not at all. The option to give Maps access to GPS all the time isn't available unless you dig deep into the settings & grant the Maps app permission separately - this is such a stupid design especially if you expect Maps or other navigation apps to just work normally as they should. Granting the app access to GPS only when the app is open doesn't work if the app isn't in the foreground - for example, if you get a call while you're driving and Maps gets minimized and the Phone app opens, then GPS & route navigation will be lost - imagine dealing with that while you're driving trying to navigate. 4. Ads - this is another infuriating issue. Why are there ads in a phone that I paid full price for, and on top of that one that is unlocked fully? There is no option to turn off ads in the settings and Samsung has very predatory setup process when you first setup your phone - it will automatically opt-in for sending them personal data and showing ads. There is a very jank way to disable ads and it's not supported natively within the Settings of the phone - in other words, you're paying over $1000 for a smartphone that will have ads. This is absurd and absolutely unnecessary. If this phone was $700 I would still be annoyed with all those things but slightly less. If this phone was $400, I probably wouldn't complain that much about most of these issues. But at over $1000, this is ridiculous at best and people should find these practices unacceptable.
